IMPROVEMENT IN PLANINGMAQHINES.

. The Schedule referred to in these Letters Patent and making part of the same.

To all @oh-om it may concern Be it known that I, LoUDUs B. WALKER, of Chicago, inthe county of Cook, and State 4of Illinois, have invented certain new and useful'lmprovements in Planing and Tongue and Growing-Machines; and do hereby declare the following to be a full, clear, and exact description thereof, reference `being had tothe 'acompanyingdrawings and tol the letters of reference marked thereon, forming part of this specification.

My invention relates to certain improvements connected with or on theadjustable table of a planing 'and tongne-andgrooviug machine; and

It consists, first, in providing the feed-table with four rollers or wheels,.to rest upon four inclines; second, inmoving the four iuclines all at one time, with one screw, for raising and lowering the table to any desired distance from thecylinder; andthird, in the l arrangement of adjustable boxes, set-screws, and rollers, that carry the inclines by means of the set-screws under each box, to raise or lower either side of thetable,to an exact line with the cutting-edge of the knives of the cylinder. y

In order to enable others skilled in the art to which my invention appertains to make and use the same, Ir will nowproceed to describe its construction and operation, referring to the annexed drawings, in which- Figure 1 is a side elevation, and

Figure 2, a plan view of my machine.

A represents the frame of my machine, across the upper portion of which is placed the cylinder B, carrying the knives 0 O. h

Below the cylinder B in the frame A is placed the feed-table D, having at each end a roller, E, carrying endless chains, &c., for feeding the material to the knives. f

Oneach side of the `table D are placed two rollers or wheels, a a, each of which rests upon an incline, b.

The four inclines bb are all connected so as to formv .one frame, Which'is moved endwise by means-of a screw, G, said-screw passingthrough the front end of the frame formed by the inclines, and through a standard, H, in the frame A. i

By turning the screw G the incline frameis moved endwise in either directiom, and as the table D is so constructed that it cannot move endwise` in the frame A, it follows that it will gradually rise or fall according to the direction in which the inclines are moved.

The rollers or wheels a a allow the table D to move on the inclines, or rather the iuclines to move under the table, without any perceptible amount of friction,

`and consequently the table can readily be adjusted at any-distance from the edges of the cutting-knives O C. -The frame formed of the four incliues b b rests upon two rollers, I I, having their bearings in adjustable journal-boxes, d d, in the frame A.

'Ihese journal-boxes are raised and lowered by means of the setfscrews c e, from underneath, so that either side of the table may be raised or lowered atV will` to bring it in an exact line with the cutting-edges of the knives on the cylinder. V

Havingrthus fully described my invention,

. What I claim as new, and desire to secure by Letters Patent, isy r y n l The combination of the table D, rollers a a, inclines b b, screw G, rollers I I, journal-boxes d d, and setscrews c e, all constructed and; arranged as described, to operate substantially in the manner and for the purposes herein set forth.v i

In testimony that I claim the foregoing, I have here- I unto set my hand this rst day of October, 1869.
